Finally, the pH value, lactic acid, water soluble carbohydrate, ammonia nitrogen and cellulose contents were determined for WH silage prepared under the suitable adding doses of lactobacillus and cellulase at day 1, 3, 5, 15, 25, 35 after ensilaging. The pH value decreased from 5.5 before ensiling to 4.3 on the 35th ensiling day, whereas the reverse change tendence was observed for lactic acid content. The cellulose content of silage was lower from 26.5%DM in raw material to 22.3%DM.
